Abstract

The utility model discloses a wafer check valve which comprises a valve body and a valve clack. A guide column is fixed onto the valve body in the diameter direction of the valve body, a spring is fixedly sleeved on the guide column, the valve clack is in a double-valve-clack form, the section of the valve clack is in the shape of a bilateral double-arch combination, and a gasket is arranged between the valve body and the valve clack. The wafer check valve has the advantages that the wafer check valve is simple in structure and high in safety, and the valve clack is not easy to deform.

Description

A kind of Wafer Check Valves
Technical field
The utility model relates to a kind of Wafer Check Valves.
Background technique
In industrial and civilian various flowing medium pipelines, adopt safety check as the original paper that prevents that fluid from flowing backwards, as spin-up formula safety check usually.But this valve seal poor-performing is prone to seepage, use a period of time after Leckage increase, and maintenance difficulty is relatively used must more renew valve in 2 years usually, and the valve body that uses at present, all inconvenience of installation and maintenance.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of simple in structure, Wafer Check Valves that flap is yielding, not safe is provided.
For achieving the above object, the technical solution of the utility model is: a kind of Wafer Check Valves, comprise valve body and flap, on the described valve diameter direction guide pillar is arranged fixedly, suit also fixedly has spring on the described guide pillar, described flap is bivalve lobe form, and the cross section of flap is symmetrical pair of arch, is provided with sealing gasket between described valve body and the flap.
Described spring is stainless steel.
The beneficial effects of the utility model are: bivalve lobe and flap arch arrange, and make flap not yielding, good working effect; The setting of sealing gasket has increased sealing, improves Security; The employing of spring stainless steel, corrosion-resistant.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: valve body 1, flap 2, guide pillar 3, spring 31, sealing gasket 4.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of Wafer Check Valves, comprise valve body 1 and flap 2, on described valve body 1 diametric(al) guide pillar 3 is arranged fixedly, suit also fixedly has spring 31 to play the leading role of flap 2 actions on the described guide pillar 3, and described flap 2 is bivalve lobe form, and the cross section of flap 2 is symmetrical pair of arch, make flap 2 not yielding, good working effect.Be provided with sealing gasket 4 between described valve body 1 and the flap 2, increased the sealing of valve, improve Security.Described spring 31 is stainless steels, plays corrosion-resistant effect.
The utility model principle when working medium when input arranged before the valve, relies on the working medium pressure before the valve to make valve opening, the working medium valve of flowing through.When stopping input media when input before the valve, upstream pressure is close to zero or be zero, and rely on behind the valve pressure of working medium that flap 2 is reliably contacted with valve body 1 and reach sealing function, thereby, work so circularly.

Claims (2)

1. Wafer Check Valves, comprise valve body (1) and flap (2), it is characterized in that: on described valve body (1) diametric(al) guide pillar (3) is arranged fixedly, described guide pillar (3) is gone up suit and spring (31) is fixedly arranged, described flap (2) is bivalve lobe form, the cross section of flap (2) is symmetrical pair of arch, is provided with sealing gasket (4) between described valve body (1) and the flap (2).
